VEHICLE-AXLE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed May 1`, 1905. Serial No. 258.232.

T0 all whom, it may concern:

Be it known that l, REBECCA BORDER, a citizen of the United States,residing at Everett, in the county of Bedford, State of Pennsylvania,have invented certain new and useful Improvements in Vehicle-Axles; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine.

This invention relates to nuts, and more particularly to means torpreventing vehiclewheels accidentally leaving their axles.

One object of the invention is to provide an exceedingly simple,inexpensive, durable, and eflicient means for positively lockingvehicle-wheels upon their axles.

Another object of the invention resides in the provision of a nut havingan extension iitted longitudinally in the axle and held therein by awedging or other locking key.

IVith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claim, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope oi the claim without departing from the spirit orsacrificing anyof the advantages ofthe present invention.

In the drawings, Figure 1 is a longitudinal sectional view of a portionof an axle. Fig. 2 is an elevation, partly in section, illustrating amodified -tor .n of nut. Fig.` 3 is an elevation of a modified form oflocking-key.

Referring now more particularly to the accompanying drawings, thereference character 1 designates an axle having the usual spindle 2,provided with a collar 3, designed to limit the inward movement oi thewheel (not shown) upon its spindle. In the present instance the spindleis provided with a central longitudinal bore 4, extending beyond thecollar 3 and into the axle 1, there being a slot 5 formed in the axle inadvance of the collar 3, the slot intersecting the said longitudinalbore 4 and extending fromthe top to the bottom of the axle.

The outer end of the shank or stem 6 ofthe nut is provided with anintegral head 7, de-

signed to abut against the outer end of the hub of a wheel, the innerend of the shank or stein having a slot 8, designed to register with theslot 5 of the axle, there being a key whose shank portionQ its thealining slots 5 and 8. The key is provided with a head 10 and has itsopposite extremity screw-thread-o ed for working iit with the ordinarynut 11, one side edge of the shank or stem of the key being taperedupwardly, as at 12, whereby the key may be wedged in the said aliningslots `and tend to draw the shank 6 into its seat or bore as the key isdriven home, and in view ot which, even if the nut 11 should becomeaccidentally displaced, the wedging action of the bolt would preventoutward movement of the stein 6. It will be observed that the slot- 5 iselongated to permit the inward drawing of the shank 6 incident to theaforesaid wedging action.

vIf desired, the outer end of the stem or shank 6 may be screw-threadedfor the reception of the flanged cap-nut 12 as shown in Fig. 2.

It will thus be seenthat the vehicle-wheel will be positively lockedupon the spindle or axle and that the means Jfor accomplishing thepurpose is very simple and inexpensive.

In Fig. 3 there is shown a modiiied form of locking-key, wherein the keyhas a shank 13, rectangular in form and not provided with the bevelededge, as in the other torm of keyin. However, this secured key 14 has atight fit with the alining slots of the axle and shank of thelocking-nut.

What is claimed is- The combination with an axle having a longitudinalbore, of a nut having a shank fitted in said bore, said axle and saidshank having registering slots, a headed key engaged through said slots,said key having a single wedge-face extending from the said head to themiddle of the key, the slot in the 'shank being of greater length thanthe width of the key adjacent to its middle, and a nut engaged upon thekey.

In testimony whereof I allix my signature in presence of two witnesses.

REBECCA BORDER.
